PATENT OFFICEo CLOTH-BEAM FOR Looms.

SPECIFICATION forming part of Letters Patent No. 342,148. dated May 18,1886.

Serial No. 157,080. (No model.)

To aZZ whom it may concern.'

Beit known that we, HARRISON UNDEE- WOOD and SI-IAnLEs SOHWETZEE both ofthe city, eounty,and State of New York, have invented certain new anduseful Improvements in OlotlrBeams for Looms, of which the following isa full, clear, and exact description.

This invention consists of a cloth-beam upon which cloth is to be woundas it is woven, and from which it is to be subsequently removed,constructed in two corresponding semicylin drcal parts attachable to anddetachable from a revolving shaft, and provided with an outer casing,substantially as hereinafter described and shown.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding pnrts in all the figures.

Figure 1 represents an end elevation of our improved cloth-beam mountedupon arevolving shaft, shown in section, on the frame of a loom forweaving. Fig. 2 represents two fragments of a sectional cloth-beam inelevation, the outer casing thereof being in section on one ofthefragments to show its thickness and the screws by which it is secured tothe beam, one of the fragments being mounted upon a supporting-shaft,towhich it is clamped. Fig. 3 represents a fragment of one end of aclothbeam, showing a clamping device thereon in elevation, by which thesectional beam is to be clamped upon a supporting-shaft, a section ofwhich shaft is also shown in elevation. Fig. 4 is a detail Viewrepresenting a hook and pin, by which the two semi-cylindrical partsforming the beam are hooked together at the ends opposite to the ends onwhich are hubs to be clamped to the shaft, the shaft being shown insection.

A in the accompanying drawings represents a shaft supported in suitablebearings on the fra-me of a loom Afor weaving cloth. Upon this shaft ismounted our improved clothbeam, which is composed of two correspondingsemi-cylindrical parts, C O', which are clamped to the shaft A by meansof two semicylindrical hubs, hy 7L', thereon, so as to be revolved toreceive the web of cloth as it is woven and delivered to the beam by theloom.

Projecting laterally from the hubs 7L Zt. are

i anges Z j, to which is fitted a clamping-screw,

D. This screw D is provided with a shoulder,

7e, and collar Z, to receive between them the flange of the hub h. Thelower end.j',of this clamping-screw D terminates with a screwthread toengage with a corresponding female screw formed in the fiangej, by meansof which the two flanges z' j are drawn together to clamp the hub formedof the two semi-cylindrical parts li h' around the shaft A, asrepresented in Fig. 1. v

In order to introduce the clamping-screw D into the flanges i j, so asto draw the two hubs 7L h together to clamp around the shaft A, theflange i is recessed,so as to receive the shank of the screw D betweenthe shoulder k and collar Z, as shown in Fig. 1.

Vhen it is desired to loosen the end pieces, a b c cZ,ofthe hubs h h',so that the beam may revolve upon the shaft independently, the collar Zserves to spread the angesi j apart when the elampingscrew D is turnedoutward, as represented in Figs. l and 2. The two semicylindrical partsC C are provided with the hubs hhnpon one of their ends only, theiropposite ends being connectedby a hook, p, and pin p', as shown in Fig.4. The semicylindrical parts O C are covered with a thin outer casing,e, of metal, with its two ends terminating at the edges of the parts C Con the side next to the clamping device, and secured to the end pieces,c b c eZ, of the parts O C by screws f along their edges, as shown inFigs. 1, 2, and 3. By this casing e the two part O O are held togetheron the side e when the hubs ZL h are loosened on the shaft A, so thatthe beam may revolve independently on the shaft and be removed therefromand replaced at pleasure.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- A clotlrbeam for looms, consisting of twocorresponding semi-cyli ndrical parts,O C,pro vided, respectively, withsectional hubs h h', projecting from their ends,with lateral flanges ij, and having a clampingscrew, D, having a shoulder, k, and collar Z,substantially as and for the purpose herein set forth.
